    Last night I could have made £90!!

    I think that for an out of hours callout on Christmas Eve, £90 (plus vat) is pretty reasonable. However, as in this case, if I was already working in the vicinity and it was an existing customer and it was a trivial job, I would have chopped the invoice price in half.

    Shower isolators - Do we need them or not?

    I agree, it doesn't really need a neon. I think the ones with a neon were cheaper than the ones without.

    Shower isolators - Do we need them or not?

    If I can, I use one of these 50A DP switches, usually in an adjacent cupboard. I also fit them for cookers where possible, again in a cupboard. Loads of space for termination of large cables and two screws per terminal. Zero risk of burning out. 50 Amp DP Switch - Oblong with Neon -...

    Settle an argument please!

    An easy check as to whether an appliance is using power is to feel it. If you can't detect any warmth, then it won't be using any significant amount of power. Remember that it will take a while to cool down after use. A modern phone charger will be taking less than 1 watt when plugged in but...

    Plug melted to dishwasher

    It's the back of the dishwasher that gets warm with the very hot water sloshing around. Anything pressed against it will sink into the soft tarry sound/heat insulation.

    SWA cable rating - 2 core or 3 core?

    If an extra core carrying no/negligible current made a significant difference to the heat dissipation, then there would be separate columns for 3 phase 3 core and 3 phase 4 core.

    SWA cable rating - 2 core or 3 core?

    If you use 3 core SWA for a single phase circuit, it won't dissipate as much heat as the same cable used for a 3 phase circuit running at the same current. I use the 'single phase' column values in the current carrying capacity tables.

    Magic gel in the cold?

    I agree. If you really have to bury it, then a resin-filled joint would be best.

    Magic gel in the cold?

    Is this really the best solution? Can a new joint box be fixed to a short post above ground?

    External columns led

    There's no requirement for RCD protection of buried SWA cable or of external light fittings.

    Pete's Videos What a way to treat a pair of pliers

    Nice one. Not seen that before, although similar to the thermite process for joining steel rails.

    What test equipment DO you have on site? AVI?

    ? Installing 2way switches into a outdoor socket circuit.

    Hmm. So, it is available, but not widely and relatively expensive.

    ? Installing 2way switches into a outdoor socket circuit.

    Interesting. Do you have a link?

    ? Installing 2way switches into a outdoor socket circuit.

    What size of 3C&E were you planning to use? I doubt if you'll find any over 1.5mm². One reason for my suggestion of alternative methods.

    ? Installing 2way switches into a outdoor socket circuit.

    Two way switching of the socket supply may be possible, subject to various considerations including voltage drop and earth fault loop impedance. There may be better ways, such as wireless control or use of an impulse relay which would allow the switching to be done in low current cable and...

    Strange things at callout

    Do you have continuity figures for the circuit? R1, Rn or R1+Rn?

    Additional sockets & lighting.

    But it has no effect on the certification required. 2 minor works or 1 EIC, as Murdoch says.

    Why do I need anything more than a Neon?

    Really need to go up to the T110 to allow elimination of 'ghost' voltages. It has switchable input impedance by pressing a switch on each probe. Drops input impedance from 200k to 7k. Fluke T110 Voltage/Continuity Tester - https://www.test-meter.co.uk/fluke-t110-voltage-continuity-tester/

    What is this and is it normal? Council electrics

    The point is that there is no special danger to the MET. It is likely to be connected to gas and water pipework, along with any metal taps, baths, sinks, boilers, etc. If the consumer unit is metal, it'll be connected to that too. So there's no additional safety to be gained by covering this...
